dolphi86 [110]

Answer:

See explanation below.

Explanation:

  • umps Na+ ions out of cell,
  • Pumps K+ ions into cell ,
  • Exchanges 3 Na ions for 2 K ions ,
  • Creates a membrane potential that is negative on the inside ,
  • The transport protein becomes phosphorylated by ATP during the transport cycle.
  • Three trans-membrane transport steps are involved in the transport of glucose from the intestine across the intestinal cell into the blood.
  1. ATP driven antiport of Na+ out of cell and K+ into cell.
  2. Symport of glucose and Na+ into intestinal cell from intestine.
  3. Uniport of glucose from the intestinal cell into the blood.

A student has a sandwich for lunch. The bread contains starch molecules and various other molecules. After chewing and swallowin
kupik [55]

Answer:

Once starch reaches small intestine, it needs to be broken down into smaller units with the help of <u>hydrolysis reaction</u>. Pancreatic amylase catalyzes this reaction which ultimately breaks down glycosidic bonds present in starch molecule to produce simpler bio-molecules like maltose, dextrin etc.

Uses of carbohydrate in body:

(1) It is primary source of energy in the body;

(2) It is required by the body for storage of energy in the form of glycogen;

(3) In plants, it is required for building cellular structures like cellulose.

Explanation:

In order for starch to be digested in the intestine, it needs to be hydrolyzed with the help of pancreatic amylase. The hydrolysis reaction breaks the glycosidic bonds of starch molecule which is a polymer leading to the release of smaller molecules like dextrin, maltose etc. Maltose which is a disaccharide is further broken down into even smaller monomeric units like glucose with the help of enzyme known as maltase.

After conversion into monomeric unit i.e. glucose now it can be absorbed by the blood stream. The blood transports these small glucose molecules to all the cells of the body. After entering the cell, the glucose is used for the production of energy/ATP via cellular respiration.

During cellular respiration, the glucose is first converted into pyruvate via glycolysis. Pyruvate then enters PDH complex wherein it is oxidatively carboxylated into acetyl coenzyme A. The acetyl coenzyme A produced then enters TCA cycle and produce high energy molecules like NADH, FADH₂ and ATP. The NADH and FADH₂ then finally enter electron transport chain (ETC) so as to produce ATPs. These ATPs are then utilized by our body for our day to day activities.

The test results below indicate the presence of which nutrient? four test tubes A. monosaccharide B. polysaccharide C. protein D
mel-nik [20]

Answer:

See below

Explanation:

Q1. incomplete information given

Q2. Protein will be present so <u>test tube C.</u> Beef is a rich source of protein. Hence, the Biuret test will be relevant in this case since that is specific to detecting proteins.

Q3. Orange juice has ample amount of simple sugars (such as fructose, glucose), which are monosaccharides. So option A. Benedict test is required here.

Q4. Incomplete information provided

Q5. You need a certain kind of food that is rich in protein and simultaneously lacks fats. Here, skimmed milk is relevant - fat has been removed from the milk although protein is still present.
